Setting up (slowly) for experiments with the ADSP 21xx based ADMCF328 chips I grabbed of internet for cheap.
First step, set up to program them from serial line.
So, rather than go feral, I pieced together the actual chips from the board from the time machine of the internet.
So, I will use my CPLD board to generate a 10MHz clk signal, rather than fiddle with a crystal. For the moment I am going to go without the NME0505S although the mixing of analogue and digital gnd may be a little fiddly. Although, this was inherited because I elected to go with the AD7306BR (an hence the opto couplers). It may have made more sense to go with a MAX232 or similar.
The initial experiments will be LED lighting and driving my LogicSniffer by the PWM pins.
